Can't enter BIOS on new system that I just built!

Hi Everyone,

I have just put a computer together, and it is not entering BIOS as normal. The BIOS boot screen is presented as below -

All of the fans (CPU & System) are running, and the computer isn't making lots of beeping noises. However it doesn't matter whether I press on DEL, F12, etc nothing happens.

Given sufficient time the computer beeps twice, beep...long pause...peep, and then it shows the screen below -

I then have to power off / on to get back to the first screen shown in this post.

I have cleared the CMOS, and I have removed the CMOS battery but still no improvement.

The motherboard is a Gigabyte X79-UP4, I am using 16 Gigs of RipjawsX, an i7 38xx and a 550 Watt power supply.

If anybody has any suggestions on how to overcome this issue they will be greatly appreciated.

Kind Regards,

Davo
